MHE High Current Low DCR Power Inductors MHE0503 Series FEATURES AND APPLICATIONS Laird MHE series high current power inductors improve performance,reliability and power efficiency. A lower power loss benefits consumer electronics, Industrial and Telecom product design. Products feature extremely low DCR with greater efficiency and enable a larger current in a small size. Inductors are of magnetic shielding and molded construction and perform in operating temperatures ranging from -40°C to 125°C (including self-heating temperature rise) FEATURES • High saturation current realized by optimum coil desigh and high performance powder • Low profile and very compact in size • Very low DCR APPLICATIONS • Industrial DC to DC power lines • Telecom and Datacom DC to DC power lines • DC to DC converter with low power loss, low voltage and high output current such as CPU ,VRM, etc PART NUMBER EXPLANATION ELECTRICAL SPECIFICATIONS • Inductance tested at 1MHz, 1.0V • Heat Rated Current (Irms) is defined based on temperature rise approximate 40°C without core loss (ambient temperature 25±5°C) • Saturation Current (Isat) is the DC current at which the inductance drops off approximately 30% from its value without current. (ambient temperature 25±5°C) • Operating temperature range: -40°C~+125°C (including self-heating temperature rise) • Storage temperature range (packaging conditions): -10°C~+40°C and RH 60%(MAX.) Note: Heat Rated Current (Irms) is tested on a typical PCB and apply a constant current in still air. The temperature rise is dependent on the application system condition including PCB PAD pattern, trace width and thickness and adjacent components etc. It’s suggested to verify the temperature rise of the component under the real operation application conditions. www.laird.com MHE0503 Series Rev:B 1.MHE0503 SERIES DIMENSIONS Recommended layout MHE0503 Series A B C D E F 5.7±0.3 5.4±0.3 3.0 Max 4.2±0.3 2.0±0.3 2.4±0.3 www.laird.com MHE0503 Series Rev:B 2.SPECIFICATION Part No. DC Inductance DC Resistance (uH) Resistance (mohm) 1MHz/1.0V (mohm) Typ Max Isat (A) Typ/Max Irms (A) Typ/Max SRF (MHz) Typ MHE0503R33M-10 0.33±20% 3.4 3.6 26.0 23.4 19.2 17.3 102 MHE0503R68M-10 0.68±20% 5.8 6.5 22.0 19.8 14.5 13.8 70 MHE05031R0M-10 1.0±20% 7.2 8.5 17.0 14.0 11.1 10.5 55 MHE05032R2M-10 2.2±20% 13.2 14.5 11.0 9.2 9.7 9.2 34 MHE05033R3M-10 3.3±20% 20.0 23.0 10.5 8.7 8.1 7.7 28 MHE05034R7M-10 4.7±20% 29.5 35.5 8.5 6.8 5.9 5.6 21 3.EQUIVALENT CIRCUIT 4.MATERIAL LIST (a) Coil (b) Core (c) Pin www.laird.com MHE0503 Series Rev:B 5.
